I don't understand why someone would want to go back once they realize it isn't the truth just so their friends and family will acknowledge them but some people take a long time before they can break free. But what kind of friends are these won't even allow you to have your own thoughts and beliefs? Open your mouth once and say something they don't like and the friendship is over again. Rather childish isn't it? One thing for sure you won't be alone the Kingdom Halls are full of people playing this game you just won't know who they are because they are living in fear of being found out. Suffering through all the boring talks five meeting a weak is one thing but how will you be able to go out in service and try to trick others into the same lifestyle? Be prepared for a lot more depression if you go back.
On the other hand, if it really is Jehovah you're there for, then the appreciation for His ways and principles will allow you to bring out the best in yourself and others around. The key is personal study, your relationship with Jehovah. Every day. If you can keep to that, you'll still get the opposition, but you'll have Jehovah on your side. And nothing can beat that. It's a matter of focusing on Jehovah's Kingdom and His will; the rest pales incomparison.
